Description
The surface leaching of the labile component of uranium was carried out in estuarine sediments of Zuari river in Goa (India). The measurements of alpha activities of 238U, 235U and 234U in the leachates indicated a remarkable anomaly between the activities of 238U and 234U. The activity ratios of 234U/238U in these leachates were found to be in the range of 1.10 to 1.14. However, the activity ratios of 235U/238U were found to be 0.045 which is close to that in natural uranium. It was observed that the anomaly between 238U and 234U exists only on the surface organic layers of the backwater sediments of the Zuari river. (author)
